ABSTRACT

The present invention provides an infant comfort system using artificial intelligence and micro-vibration and a method for controlling the same, the system including a bouncer seat on which an infant can be laid prone in a bouncer to allow the infant to have a stable resting posture similar to that in his/her mother&#39;s womb, in contrast to a conventional bouncer on which an infant is laid supine, thereby making the infant feel stable and comfort and thus easily making the infant stop crying.

TECHNICAL FIELD

The present invention relates to an infant comfort system and a method of controlling the same. More particularly, the present invention relates to an infant comfort system using artificial intelligence and micro-vibration according to a frequency of an infant crying sound and a method of controlling the same.

BACKGROUND ART

The term “infant comfort system” refers to a product used when infants are taken care of and includes products such as a bouncer, a baby band, and the like. A bouncer looks like a chair and means infant goods like a rocking chair. The bouncer is usually used when putting infants to sleep or soothing the infants, and soft vibrations thereof help infants feel comfortable like they are in their mother's arms.

On the other hand, it is known that infants transfer various communicative expressions or signals such as crying, and understanding and appropriately responding to signals contained in an infant crying sound is an important part in taking care of infants. Since studies have shown that leaving crying infants alone affects the brain badly, it is important to cope with the infant crying sound for healthy growth thereof. In addition, in order to solve such a problem, there is an increasing need for a bouncer that can quickly soothe crying infants without a person directly hugging and soothing the infants.

The existing bouncer products generally have a form in which the infant is laid supine so as to face the ceiling, and some products are shaken by the movement of the infant or shaken in such a manner to be controlled by the fully automatic motion. FIG. 1 is a photograph showing an example of the existing bouncer product. As shown in FIG. 1, the existing bouncer product generally has a structure in which the infant is laid supine so that the back of the infant is against the bouncer seat. Examples of related art of such a bouncer include Korean Patent No. 10-1675647 (Invention title: Portable Bouncer) and Korean Patent No. 10-1636971 (Invention title: Combined bathtub and bouncer for infants).

However, there are many cases where the user does not stop infant crying even when using the existing bouncers. Particularly, there is a problem in that the existing bouncers cannot properly cope with why infant is crying. It is necessary to develop a bouncer that can solve the problem.
